A look at Zuckerberg's Facebook page reveals that he is now "Married to Priscilla Chan." That was not the case yesterday, the day that the company went public in a spectacularly hyped IPO that may have ended up a bit of a dud.

"Zuckerberg and 27-year-old Priscilla Chan tied the knot at a small ceremony at his Palo Alto, Calif., home, capping a busy week for the couple," a guest authorized to speak for the couple told the Associated Press. "The person spoke only on the condition of anonymity."

The AP reported that the guests had been under the impression they had been called together to celebrate Chan's graduation. After they arrived, they found out that the event was, in fact, a wedding ceremony.
